Product Details

HDPE corrugated optical fiber duct (C.O.D) is made of polyethylene, which is compound extruded with a ribbed wall pipe or silicon core pipe with an extremely low friction coefficient as the inner pipe and a high-pressure resistant, easy-to-bend corrugated pipe as the outer pipe. Its comprehensive performance is incomparable to any previous optical cable protection pipes.

With excellent physical and chemical properties, a perfect structural form, low manufacturing cost and convenient construction, C.O.D pipes have become the first choice for optical cable protection pipes under various topographical conditions, providing a reliable protection solution for optical fiber communication engineering.

C.O.D pipes have a trend of gradually replacing the traditional optical cable protection pipes, making them the most advanced and reliable solution available for modern optical fiber infrastructure.

Frequently Asked Questions

Q What is HDPE corrugated optical fiber duct (C.O.D)?

HDPE corrugated optical fiber duct (C.O.D) is a dual-layer protective pipe made of polyethylene. It features a low-friction silicon core or ribbed inner pipe for smooth cable installation, and a high-pressure resistant corrugated outer pipe for mechanical protection. It is specifically designed to protect optical fiber cables in various installation environments.

Q What are the main advantages of C.O.D pipes over traditional optical cable protection pipes?

C.O.D pipes offer superior physical and chemical properties, including high-pressure resistance, excellent flexibility, ultra-low inner friction, corrosion resistance, and lower manufacturing costs. These combined advantages make them far more versatile and durable than conventional optical cable protection pipes, and they are gradually replacing traditional options across the industry.

Q What topographical conditions are C.O.D pipes suitable for?

C.O.D pipes are suitable for a wide range of topographical conditions, including flat terrain, mountainous regions, curved pathways, and underground installations. Their flexibility and high-pressure resistance make them adaptable to virtually any environment encountered in optical fiber communication engineering projects.

Q Why is the inner pipe of C.O.D designed with a low friction coefficient?

The low-friction inner pipe — either a silicon core pipe or ribbed wall pipe — reduces resistance during optical cable pulling and installation. This allows cables to be threaded through longer duct runs with less force, reducing installation time, labor costs, and the risk of cable damage during the process.

Q Is HDPE material safe and durable for long-term underground use?

Yes. High-Density Polyethylene (HDPE) is highly resistant to chemicals, moisture, soil corrosion, and UV degradation. It maintains its structural integrity over decades of underground use, making it one of the most reliable materials for long-term optical cable protection in demanding environments.

Q Can C.O.D pipes be used for both direct burial and conduit installations?

Yes. C.O.D pipes are versatile enough for direct burial, duct-within-duct configurations, and various conduit installation methods. Their corrugated outer structure provides excellent crush resistance for direct burial, while their flexibility supports routing through existing conduit systems or along complex pathways.
